What have you seen?

I'm mapping one on the rollers right now and it's making really good power, no dodgyness with the rollers either as its been tested in shootout mode.

This is the spec:

Newly built engine by myself..

7.4:1 comp (he wants more power in the future)
Siemens 3102's
BD14 In cam
Lightly ported head (read de-bured!)
Double valve springs
Long studded
MLS gasket
Big intercooler
Noisy 3" exhaust (very small o/d rear silencer)

Running 35psi peak boost tailing to 28 6k and 24

What would you expect to see at the wheels? (mapped on a rolling road )

Jay,

iTrader: (4)

if IF its mapped right id say around 330+ just

edited its 4x4 isnt it ?

fish99

is 380bhp too much on a T34?

Jay,

iTrader: (4)

not at the fly but at the wheels id say so

Spiky

iTrader: (1)

294 at the wheels?

CossieRich

iTrader: (1)

I made 453 fly and 386 at the wheels - 2wd saff with GT30

So i will have a guess at 330 at the wheels

Chip

iTrader: (3)

@ not mentioning if its 4wd or rwd, kind of an important detail that martin.

Im going to guess at 340 rwd, 320 4wd

Bobby Singh

I made 280ish hp @ wheels 4x4 T34 .48, CR 7.8:1

twinkle_2k86

Aren`t all Escos 4x4 then????

Jay,

iTrader: (4)

some get converted to rwd

Chip

iTrader: (3)

All 3 doors are rwd, but not some reyland ones, with Martin you never can tell

Some of his escos's he's done are v8 and rwd, so YB and rwd would hardly pose him a challenge

CossieRich

iTrader: (1)

Come on then Martin. We have guessed. Whats the figures?

Jay,

iTrader: (4)

he wont say its not at page 6 yet

CossieRich

iTrader: (1)

lol Jay

Bart

343 ATW

BRAMMER

iTrader: (23)

i say 370 @ fly

CossieRich

iTrader: (1)

thats a great guess when Martin asked for at the wheel figure

Martin-Hadland

iTrader: (2)

Read the title, dognut

BRAMMER

iTrader: (23)

I don't know how to work it out ATW's so maybe you could help bigshot

Jay,

iTrader: (4)

right i know im not the sharpest knife in the draw but it doesnt say if its 2 or 4 wd martoon when it could be either !! DETAILS MARTIN its in the detail

or is this a attempt to get it to page 6

Martin-Hadland

iTrader: (2)

But if it was not a standard type transmission Escos then I would have mentioned it

Anyhow at the moment it's making 339.5 @ the wheels

Lambchop

iTrader: (1)

firstly, fuck me if someone says t34 escos you HAVE to presume 4x4 as they were built like that. To assume otherwise would be silly and i'm sure Martin would've said had it been different

anyway...sounds interesting as the spec is very similar to mine except im 7.2:1, and hold similar boost but on a .55 housing. oh and mine is greys.

I'd like to think mine was 380-400 bhp, say 320-340@wheels and 4x4 usually 20 or so behind so say 300-320@wheels?

Lambchop

iTrader: (1)

excellent!

Jay,

iTrader: (4)

im deleting this post it peaked to early in the thread


so it worked then

Martin-Hadland

iTrader: (2)

Like a dream !!

Garage19

How long will a T34 last when try to make power like that?

Surely it must be seriously overspeeding the limits that Garrett would recomend?

What effect does this have on life time?

Would a larger compressor not be more suitable?

Porkie

iTrader: (1)

Nice guess Chip!

Garage19

So what worked or is it secret squiral?

Jay,

iTrader: (4)

absolutely spanking and i was nearly there to lol

Chip

iTrader: (3)

I was out by 20bhp mate.

I said I thought 340 if it was rwd.

Its 4wd, which I guessed at 320.


So im well impressed with the figures personally

Chip

iTrader: (3)

Cant beleive you are even bothering to ask that on page 1, thats a page 4 or 5 kind of question

Porkie

iTrader: (1)

ooops

Jay,

iTrader: (4)

secret reyland ear muffs i think

Jay,

iTrader: (4)

very rarely you dont see a 34 over spooled tbh but seems alot of people are still scared of the reliability of a gt30 but imo a unstressed gt30 will still be more reliable than screaming the tits out of a t34

Chip

iTrader: (3)

Agreed.

Ideal turbo for just over 400bhp IMHO is a GT3071 with a 63 back housing and a 4" surge ported front end, slightly smaller version of CossieRich's basically.

T34 has over advantage though, like not needing a dump valve and being cheaper to rebuild.

Bart

I was closest, whats my price? lol

Mike Rainbird

iTrader: (3)

If use aggressively, it will be spitting exhaust blades every 3 months, as that is the exact pressure I ran mine at .

Back it off to a peak of 30psi, and it should be fine (albeit lower powered). Would be interesting to see by how much .

Jay,

iTrader: (4)

u get to make the next cupa

Benni

Dennis asked me to forward on his question, as he cannot reply right now because he is having a cup of tea with Henry Ford on the Moon. He would like to knw why so little power? He said their is another 150bhp in this Turbo.

On a serious note, didn't seem to take you long to pick up mapping, nice one.

Benni.

Chip

iTrader: (3)

He certainly seems to have got the hang of the flatout stuff now if its making that much power, thats the easy bit of mapping though, lol


Martin what ECU is it on?
